29 A-List Actors You Probably Didn't Even Notice Were In An Old TV Show Or Movie Because They Only Played Small Roles Back Then

There are now many actors in Hollywood who have long cemented their reputations as truly talented individuals in their craft, and it's mind-boggling to see them in such minor roles when they were just starting out. Sometimes, when you put on an old comfort movie, you may be surprised by some of the people shown on-screen—because you never realized that they actually starred alongside some now-A-listers in Hollywood.

It would be strange to see such big celebrities like Angelina Jolie or Johnny Depp playing a tiny role in a movie; but hey, every successful person started out somewhere, right? One way or another, it can be nerve-wracking to prepare yourself for a movie night and then end up being surprised that you actually did not notice a very famous celebrity on the screen, even if you have watched it over ten times already.

For celebrities who weren't born into fame, they had to work twice as hard as those we call "nepo babies." The likes of Jennifer Aniston, Leonardo DiCaprio, and Morgan Freeman, among others, did not just appear out of thin air—they had to work their way up to achieve the kind of fame and success they have now.

That being said, take a look at these ultra-famous celebrities who you probably did not notice in the minor roles they played in older TV shows and movies because they were still relatively unknown back then:

1. Alison Brie played Jackson's girlfriend on Hannah Montana:
